-800 Fig. 8.14: A movable pulley an inclined plane same e. A load of 500 N is lifted to the height of 18 m by applying through the distance of 27 m. If the effort applied is 400 N, calculate the efficiency of the simple machine. If the same load is to be lifted to the height by using effort of 300 N keeping the efficiency constant , calculate the length of the slope. [222.857 N] 152 पाठ्यक्रम विकास केन्द्रबाट स्वीक​
